I checked my antennas for expired spiders. They get a bit testy when you
flip them over to check the date code!

We can run as high as 14.5 VDC at the controller. If the level drops below 13.8 VDC The capability is compromised. Also if any foilage or insects breach the insulators on the Hi-Z elements the system can be compromised, It took quite a while for one of our customers to find the expired spider.
